Chemical Engineering

Chemical engineering is part of a rapidly expanding field that requires interdisciplinary engineers educated in both the molecular and medical sciences. For every discovery made in the health and industrial sectors, a chemical engineer finds a way to develop and implement it on a large scale.

The PhD in Chemical Engineering program at the School of Engineering prepares you to fulfill that role. Our curriculum offers an advanced course of study to refine your research skills, and we teach you the problem-solving skills to surmount any problem along the way.

Our PhD program in Chemical Engineering is designed to outfit you with expert knowledge of the field’s core fundamentals as well as the latest research in its subtopics. By doing so, we further your specialization beyond a master’s degree, helping you achieve superior competence in a minor topic within chemical engineering.

Admission Requirements

A BS degree in chemical engineering or a related field of science or engineering is generally required for admission to graduate study. If you earned a bachelor’s degree from a foreign institution, you must submit Graduate Record Examination (GRE) and TOEFL scores. Applicants with degrees in other fields or from other colleges may be admitted with undergraduate or graduate deficiencies as evaluated by the graduate adviser. You will need to have had at least one course in differential equations.


You must complete a minimum of 75 credits of academic work past the bachelor’s degree, including a minimum of 45 credits of dissertation research, to complete the PhD in Chemical Engineering program. Although you may elect to take more than 45 credits of PhD thesis, only 45 of those credits can be counted in the required 75 credits. Furthermore, of those 45 credits, at least 36 must be taken beyond MS thesis and at the School of Engineering. A minimum of 30 graduate credits beyond the bachelor’s degree (not including PhD or MS thesis credits) are required in chemical engineering subjects, of which at least 12 must be taken at the School of Engineering. Attendance is required at departmental seminars for at least 4 semesters.

You must also pass a comprehensive qualifying examination in chemical engineering and present a doctoral dissertation. The qualifying exam is given once a year. Additional details on the qualifying examination should be obtained from your graduate adviser.

To meet graduation requirements, you must have an overall B average in all courses, excluding thesis, and must not obtain more than 2 grades of C in required subjects. Candidates for the degree Doctor of Philosophy in Chemical Engineering should plan their programs in accordance with the requirements below.
